“If I do that, it will spiral out of control very quickly. I've lost the privilege of being able to drink responsibly"

Demi has also spoken about other struggles around self esteem and mental health, but she has suggested that she’s struggled more with alcohol and drugs than her eating disorder.

Demi's family and early childhood

The American singer has suggested that her father’s death in 2013 made things much more difficult to deal with.

Speaking with American TV host Dr Phil earlier this year, Demi said that a lot of her struggles with addiction had to do with “unresolved issues” with her “birth father”, who she apologises to in the song Sober. Her mother later remarried.

Her father, Patrick Lovato, also suffered from mental health problems.

She dedicated a song to her dad on her fifth album, Confident, where she described him as a “troubled man”.

In the interview, Demi got emotional when talking about her eating disorder, which she described as “everlasting” and something she “still works on”.

She also spoke about suicidal thoughts she experienced at a young age saying “the very first time I was suicidal was when I was seven.”

This was before describing her “fascination with death” early in her life.

Demi spent time at Timberline Knolls, a residential treatment centre in Illinois, USA.

After her stint in rehab, she admitted she still struggled with alcohol and cocaine, even smuggling the substance onto aeroplanes.

At one point she couldn’t go longer than “30 minutes to an hour” without the Class A drug.

Demi has also spoken of struggles with self harm - issues which started at a young age for the star.

In a very honest chat with Dr Phil in March this year, she admitted during difficult times in the past she “turned to cutting”.
